Radar sensor for bulk solids
The Vegapuls 69 sensor is a big step closer to the ideal of an all-round radar level measuring instrument for bulk solids.
The level transmitter operates at a frequency of 79 GHz, which allows a considerably better focusing of the t transmitted signal. In containers and silos w with many internal obstructions, this e enhanced focusing helps reduce t the influence of background ‘noise’. T This means that reliable measurement i is also possible even with complex internal s structures.
New microwave components allow t the sensor to detect even the smallest of r reflected signals. Even products, which u until recently were very difficult to measure b because of their poor reflective properties ( (such as plastic powders or wood chips) can n now be measured with very high reliability.
This considerably extends the application r range for radar technology in the bulk s solids industry and opens up new a application areas as well.
With a measuring range of up to 120 m metres and an accuracy of ±5 mm, t the sensor has sufficient performance c capability even for the out of the ordinary
tasks, such as level gauging in mine shafts or distance measurement on conveyor systems.
Despite its large measuring range, the sensor is also an ideal solution for small hoppers or containers; the different antenna designs enable the optimum solution to meet the application needs.
Completely unaffected by dirt and build-up, the lens antenna guarantees maintenancefree operation even in harsh environments.
To make set-up and commissioning easier, an intelligent app for smartphones has been developed. It allows quick and easy alignment of the sensor on a swivel holder.
